[BUG] car stripped when completing missions bug?

I've had this happen a couple times. I'll talk to a person to complete a sub mission and when I come back all the wheels on my buggy are gone. Not flat, Gone!

The first time it happened, I parked it in the city. I laughed. It looked like cars stripped in bad neighborhoods. almost didn't think it was a bug. But it is annoying as the only way to fix it is to abandon that car or reload a previous save.

edit: after having this happen a few more times I've learned it's actually the wheels sinking into the ground. So not disappearing.
